Abstract: A flow meter for measuring the volume of fluid flowing through the meter includes an inner cylindrical tube through which the fluid flows and an outer cylindrical tube tending over the inner cylindrical tube. The outer cylindrical tube is radially spaced from the cylindrical inner tube to provide an annular cylindrical space between the inner cylindrical tube and the outer cylindrical tube. A seal between the inner cylindrical tube and the outer cylindrical tube closes the annular cylindrical space adjacent ends of the annular cylindrical space. The inner cylindrical tube further defines at least one opening in a wall of the inner cylindrical tube to balance the fluid pressure in the annular cylindrical space with the pressure in the inner cylindrical tube. A torus wedge flow restriction member is integrally formed within full internal circumference the inner cylindrical tube for restricting the flow of fluid through the inner cylindrical tube and produces a pressure drop in the fluid as it flows past the flow restriction member. The inner cylindrical tube and the outer cylindrical tube in combination further define at least one port for receiving a pressure sensing device to measure the pressure of the fluid flowing through the flow meter.

Abstract: A fluid densitometer for measuring the density of fluid includes an inner tube and outer tube. A sensor assembly passes through the outer tube to contact an outer radial surface of the inner tube. The inner tube is vibrated at a predetermined frequency, and detected resonance signals are used to determine fluid density.

Abstract: A fluid flow meter includes a flow meter body with a central flow passage and flow restriction opening defined therein. Fluid pressure is measured at the flow restriction opening and compared to fluid pressure measured at an upstream point. An annular flow region is defined within the flow meter body radially between the flow restriction opening and a pressure detection port.

Abstract: A mounting plate is disclosed that is adapted to be positioned between a main flow line and at least two differential pressure transmitters, to place the two differential pressure transmitters in fluid communication with a pair of pipeline taps on opposite sides of a flow reducing orifice plate in the main flow line is disclose. The mounting plate includes a plate-like body generally rectangular in cross section along its longitudinal axis and longer than it is wide along its transverse axis. The plate-like body includes a pair of ports that extend through the body and are in fluid communication with the pair of pressure taps with the longitudinal axis of the body parallel to the main flow line. A plurality of passageways or bores extend into the body to connect the ports to various combinations of pressure transmitters. One or more mounting holes for the transmitters are on a line that intersects the longitudinal axis of the body at an angle to allow some of the passageways or bores to be drilled straight and parallel to the longitudinal axis of the body between the mounting holes. In another embodiment, a sub plate is used to supply pressure to a third pressure transmitter. In another embodiment, a plate-like adapter, as well as the sub plate, is used to mount four differential transmitters or three differential pressure transmitters and a static pressure transmitter.
